Title: Phase velocity control method and phase velocity control structure of electromagnetic wave
Inventor: TANI MASAHIKO
IPC: H01P3/20
Filed: 2013-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a method capable of easily controlling a phase velocity of an electromagnetic wave at a low cost.SOLUTION: The method for controlling a phase velocity of an electromagnetic wave radiated from electromagnetic wave irradiation means prepares a parallel plate waveguide having at least a surface to propagate the electromagnetic wave thereon formed from a metal that generates surface plasmon coupling, and introduction means for introducing the electromagnetic wave to the parallel plate waveguide. A width of the parallel plate waveguide is made equal to or less than a wavelength of the electromagnetic wave. Surface roughness of the parallel plate waveguide on which the electromagnetic wave is propagated is changed, and thereby an effective refractive index of the parallel plate waveguide with respect to the electromagnetic wave is changed. Thus, the phase velocity of the electromagnetic wave introduced from the introduction means to the parallel plate waveguide is controlled.
